She may be aggressive about this, so be ready to hand over your phone.
She wants to check your messages and photos and interrogate you about every female name and photo.
They know as a foreigner in Korea you attract a lot of attention and they may assume that you must have many girls chasing you.
They will certainly start any relationship with suspicion. Early on, you may find that your new girlfriend will want to check your phone for evidence of you seeing another woman.
If you are stubborn and insist on not showing your phone, she will eventually get her hands on it and check it whether you like it or not.
Some Korean women, especially older ones, tend to have a fantasy of meeting a foreigner and escaping patriarchal Korean society. You are clearly a more positive alternative than marrying a Korean guy and having to deal with an evil Korean mother-in-law or other intrusive family members.
I suggest you be clear early in the relationship about your future plan about returning home and if that plan includes her.When a Korean girl dates a foreigner, they are scared that their new boyfriend may think they are easy.So, Korean women may be more cautious dating a foreign man than when dating a Korean man.The curfew time depends on the woman, but don’t be surprised if you are dating a girl who is 25 and she insists she has to be home by 10pm.Usually, Koreans do not introduce their boyfriend or girlfriend until they are ready to marry.If you decline her requests to see your phone, then you are automatically guilty as a womanizer.
